Anterior Chamber - CORRECT ANSWER-The space in front of the iris and behind the cornea.
Antimetropia - CORRECT ANSWER-One eye nearsighted; the other farsighted.
Antioxidants - CORRECT ANSWER-Micronutrients which destroy or neutralize free radicals,
molecules which have been implicated as one causative factor in the simulation of abnormal
cellular reproduction (cancer) and cellular destruction (aging).
Anti-Reflective Coating - CORRECT ANSWER-Anti-reflective coatings reduce glare and enhance
your appearance by removing distracting reflections.
Aphakia - CORRECT ANSWER-Condition of the eye with crystalline lens removed or missing due
to trauma. Also refers to post-cataract patients who have had cataract surgery.
Aphakia Spectacles - CORRECT ANSWER-Thick, plus-powered eyeglasses that were once the
standard optical correction following extraction of cataract. The glasses were cumbersome and
greatly distorted peripheral vision. Today, an intraocular lens (IOL) is implanted in the eye after
the cataract is removed to replace the focusing power of the natural lens eliminating the need
for aphakic spectacles.
,Aqueous Humor - CORRECT ANSWER-Also known as aqueous fluid: clear, watery fluid that flows
between and nourishes the lens and the cornea.
Arteriosclerosis - CORRECT ANSWER-A chronic disease of the arteries characterized by the
thickening or hardening of the arterial walls impairing blood circulation.
ARMD (Age Related Macular Degeneration) - CORRECT ANSWER-Degeneration of the
photoreceptors in the macular (central) region of the retina resulting in decreased central
vision.
Asthenopia - CORRECT ANSWER-A group of symptoms generally referred to as "eye strain."
Included are: headaches, tearing, "tired eyes," itching, burning and blurred vision.
Astigmatism - CORRECT ANSWER-A condition that occurs when the front surface of the eye (the
cornea) is slightly irregular shape prevents light from focusing properly on the back of the eye
(the retina). As a result, vision may be blurred at all distances.
Astigmatic Keratotomy (AK) - CORRECT ANSWER-An incisional refractive surgical technique in
which transverse incisions are made in the cornea to reduce or eliminate astigmatism.
Bifocal Lens - CORRECT ANSWER-Lens with two focal lengths, one for distance and one for near.
Usually the distance correction is on top and the correction for near is on the bottom.
Binocular Vision - CORRECT ANSWER-The simultaneous use of the two eyes. Yields a
stereoscopic image and depth perception.
Blended Lens - CORRECT ANSWER-While traditional multifocal lenses have a line in the middle
of the lens, progressive lenses are line-free. The power gradually changes from distance
correction to intermediate vision (at arm's length), to near vision (at reading distance), moving
invisibly from the top to the bottom of the lens.
, Blind Spot - CORRECT ANSWER-1 ) A small area of the retina where the optic nerve enters the
eye; occurs normally in all eyes.
2 ) Any gap in the visual field corresponding to an area of the retina where no visual cells are
present.
Cataract - CORRECT ANSWER-Clouding of part or all of the lens inside the eye, resulting in
blurred or distorted vision.
Cataract Lens - CORRECT ANSWER-Lens used following cataract; once widely used for post-
cataract patients; however, IOL (intraocular) lenses are now the most commonly used
replacement for the removal of crystalline lens, eliminating the necessity for cataract lenses.
Cathode Ray Tube (CRT) - CORRECT ANSWER-The monitor or display screen of a computer.
Special computer eyeglasses are available to increase or enhance vision while viewing computer
screens.
Choroid - CORRECT ANSWER-The layer in the eye filled with blood vessels that nourishes the
retina.
Chromatic - CORRECT ANSWER-Of or pertaining to color.
Ciliary Muscle - CORRECT ANSWER-The eye's focusing muscle that allows the crystalline lens to
perform its function of accommodation.
Coloboma - CORRECT ANSWER-A defect of the iris caused by a failure of the eyeball to fuse
properly during fetal development. These are developmental anomalies and do not worsen as
the child grows older.
